We want the coin to land on heads on 5 out of 5 flips.
Each time, the coin has a 1/2 chance of landing on heads.
Since we want it to land on heads 5 times in a row, we multiply 1/2 five times to get the probability.
(1/2) * (1/2) * (1/2) * (1/2) * (1/2) = 1 / (2*2*2*2*2)
= 1 / 32
There is a 1/32 chance of landing heads five times in a row.
Have an awesome day! :)
they are similar because 7/5 = 21/15
7/5 = 1.4
21/15 = 1.4
Answer:
a(1) = 10
a(n) = a(n-1)·0.6
Step-by-step explanation:
The first term of the sequence is the one listed first: 10. That means a(1) = 10.
The next term of the geometric sequence will be the first term multiplied by the common ratio. That ratio can be found as the ratio of the second term to the first:
r = 6/10 = 0.6
So, the recursive formula is ...
a(n) = a(n-1)·r
a(n) = a(n-1)·0.6
